Had to show ID to buy a can of computer duster today and it hit me that I'm old enough to do a lot of stuff now, like buy myself pseudoephedrine when I'm sick or check into a hotel. But then it got me thinking, why do I need an ID to do these things anyway? I kinda get needing some sort of identification when you're buying pseudoephedrine, but why do I need to be 18?

@Ocean22 Guy at CVS said it was because it's an inhalant and all the cool kids are huffing it nowadays, but I don't remember needing an ID to buy spray paint so maybe the bomb concern is a little more valid
